BACKGROUND OF THE INVENTIONThe present invention relates to an apparatus and method for providing an indication of programs and/or activities pertaining to a user and, more particularly, to such apparatus and method which provides an indication of television programs watched and/or to be watched by a user, activities performed and/or to be performed by the user, and so forth for display on a display device.[0001]
Today, due to busy schedules, people often do not have time to write or telephone family members or friends regarding day to day events such as television programs they watched or are planning to watch, activities such as sporting events and the like in which they have participated or are scheduled to participate, and so forth. As a result, people may not share comments pertaining to such television program(s) or activities with other family members or friends.[0002]
Similarly, due to their busy or conflicting schedules, family members within a household may be unable to watch television programs together. As such, children may watch television programs without their parents. Accordingly, parents may not know what programs their children have watched.[0003]
OBJECTS AND SUMMARY OF THE INVENTIONIt is an object of the present invention to provide an apparatus and method which enables one or more family members or friends to easily inform others as to television programs they watched and/or are planning to watch.[0004]
Another object of the present invention is to provide an apparatus and method which enables parents to know what television programs their children have watched.[0005]
A further object of the present invention is to provide an apparatus and method which enables a person to easily provide other people with a schedule or listing of activities in which he or she will participate and/or has already participated.[0006]
A yet further object of the present invention is to provide an apparatus and method as aforesaid wherein the television programs and/or the activities are available for display on a display unit in a predetermined format.[0007]
A still further object of the present invention is to provide an apparatus and method as aforesaid which enables a user to insert comments into the display of the television programs and/or activities.[0008]
An aspect of the present invention is to provide a television program apparatus comprising a device for obtaining information regarding a number of television programs watched by a viewer, a circuit for producing a viewer program signal representative of each television program watched by the user arranged in a predetermined manner, and a device adapted to be coupled to a television unit for enabling the viewer program signal to be supplied to the television unit so as to enable an indication of each the television program watched by the viewer to be displayed thereon in the predetermined manner.[0009]

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTSThe preferred embodiments of the present invention will be described with reference to the accompanying drawings. Referring to FIG. 1, a block diagram for an exemplary interactive cable or satellite television (TV)[0016]system100 is shown. Thesystem100 includes, at a head end of theservice provider10, amedia server12 for providing, on demand, movies and other programming obtained from amedia database14. Themedia server12 might also provide additional content such as interviews with the actors, games, advertisements, available merchandise, associated Web pages, interactive games and other related content. Thesystem100 also includes an electronic programming guide (EPG)server16 and aprogram listing database18 for generating an EPG. Set-top box22 can generally provide for bi-directional communication over atransmission medium20 in the case of acable STB22. In other embodiments, bi-directional communication can be effected using asymmetrical communication techniques possibly using dual communication media--one for the uplink and one for the downlink. In any event, the STB22 can have its own Universal Resource Locator (URL) assigned thereto to provide for addressability by the head end and users of the Internet.
The[0017]media server12 andEPG server16 are coupled bytransmission medium20 to set top box (STB)22. Thetransmission medium20 may include, for example, a conventional coaxial cable network, a fiber optic cable network, telephone system, twisted pair, a satellite communication system, a radio frequency (RF) system, a microwave system, other wireless systems, a combination of wired and wireless systems or any of a variety of electronic transmission mediums. In the case of a cable television network,transmission medium20 is commonly realized at the subscriber's premises as a coaxial cable that is connected to a suitable cable connector at the rear panel of theSTB22. In the case of a Direct Satellite System (DSS), the STB22 is often referred to as an Integrated Receiver Decoder (IRD). In the case of a DSS system, the transmission medium is a satellite transmission at an appropriate microwave band. Such transmissions are typically received by a satellite dish antenna with an integral Low Noise Block (LNB) that serves as a down-converter to convert the signal to a lower frequency for processing by the STB.
The[0018]exemplary system100 further includes aTV24, such as a digital television, having adisplay26 for displaying programming, an EPG, etc. The STB22 may be coupled to the TV24 and various other audio/visual devices26 and Internet Appliances28 by anappropriate interface30, which can be any suitable analog or digital interface. In one embodiment,interface30 conforms to an interface standard such as the Institute of Electrical and Electronics Engineers (IEEE) 1394 standard. TheSTB22 may include a central processing unit (CPU) and memory such as Random Access Memory (RAM), Read Only Memory (ROM), flash memory, mass storage such as a hard disc drive, floppy disc drive, optical disc drive or may accommodate other electronic storage media, etc. Such memory and storage media is suitable for storing data as well as instructions for programmed processes for execution on the CPU, as will be discussed later. Information and programs stored on the electronic storage media or memory may also be transported over any suitable transmission medium such as that illustrated as20. STB22 may include circuitry suitable for audio decoding and processing, the decoding of video data compressed in accordance with a compression standard such as the Motion Pictures Experts Group (MPEG) standard and other processing to form a controller or central hub. Alternatively, components of the STB22 may be incorporated into theTV24 itself, thus eliminating the STB22. Further, a computer having a tuner device may be equivalently substituted for the TV24 and STB22.
By way of example, the STB[0019]22 may be coupled to devices such as a personal computer, video cassette recorder, camcorder, digital camera, personal digital assistant and other audio/visual or Internet related devices. In addition, a data transport architecture, such as that set forth by an industry group which includes Sony Corporation and known as the Home Audio-Video Interoperability (HAVi) architecture may be utilized to enable interoperability among devices on a network regardless of the manufacturer of the device. This forms a home network system wherein electronic devices and Internet appliances are compatible with each other. The STB22 runs an operating system suitable for a home network system such as Sony Corporation's Aperios™ real time operating system. Other operating systems could also be used.
The[0020]STB22 includes an infrared (IR)receiver34 for receiving IR signals from an input device such asremote control36. Alternatively, it is noted that many other control communication methods may be utilized besides IR, such as wired or wireless radio frequency, etc. In addition, it can be readily appreciated that theinput device36 may be any device suitable for controlling theSTB22 such as a remote control, personal digital assistant, laptop computer, keyboard or computer mouse. In addition, an input device in the form of a control panel located on theTV24 or the STB22 can be provided.
The[0021]STB22 may also be coupled to an independent service provider (ISP)host38 by a suitable connection including dial-up connections, DSL (Digital Subscriber Line) or thesame transmission medium20 described above (e.g. using a cable modem) to, thus, provide access to services and content from the ISP and the Internet. TheISP host38 provides various content to the user that is obtained from acontent database52. STB22 may also be used as an Internet access device to obtain information and content from remote servers such asremote server48 via the Internet44 usinghost38 operating as an Internet portal, for example. In certain satellite STB environments, the data can be downloaded at very high speed from a satellite link, with asymmetrical upload speed from the set-top box provided via a dial-up or DSL connection.
Referring now to FIG. 2, a typical system configuration for a digital set-[0022]top box22 is illustrated. In this exemplary set-top box, thetransmission medium20, such as a coaxial cable, is coupled by a suitable interface to atuner102.Tuner102 may, for example, include a broadcast in-band tuner for receiving content, an out-of-band tuner for receiving data transmissions and a return path tuner for providing an OOB return path for outbound data (destined for example for the head end). A separate tuner (not shown) may be provided to receive conventional RF broadcast television channels. Modulated information formatted, for example, as MPEG-2 information is then demodulated at ademodulator106. The demodulated information at the output ofdemodulator106 is provided to a demultiplexer anddescrambler circuit110 where the information is separated into discrete channels of programming. The programming is divided into packets, each packet bearing an identifier called a Packet ID (PID) that identifies the packet as containing a particular type of data (e.g. audio, video, data). The demodulator anddescrambler circuit110 also decrypts encrypted information in accordance with a decryption algorithm to prevent unauthorized access to programming content, for example.
Audio packets from the demultiplexer[0023]110 (those identified with an audio PID) are decrypted and forwarded to anaudio decoder114 where they may be converted to analog audio to drive a speaker system (e.g. stereo or home theater multiple channel audio systems) or other audio system116 (e.g. stereo or home theater multiple channel amplifier and speaker systems) or may simply provide decoded audio out at118. Video packets from the demultiplexer110 (those identified with a video PID) are decrypted and forwarded to avideo decoder122. In a similar manner, data packets from the demultiplexer110 (those identified with a data PID) are decrypted and forwarded to adata decoder126.
Decoded data packets from data decoder[0024]126 are sent to the set-top box's computer system via thesystem bus130. A central processing unit (CPU)132 can thus access the decoded data fromdata decoder126 via thesystem bus130. Video data decoded byvideo decoder122 is passed to agraphics processor136, which is a computer optimized to process graphics information rapidly.Graphics processor136 is particularly useful in processing graphics intensive data associated with Internet browsing, gaming and multimedia applications such as those associated with MHEG (Multimedia and Hypermedia information coding Experts Group) set-top box applications. It should be noted, however, that the function ofgraphics processor136 may be unnecessary in some set-top box designs having lower capabilities, and the function of thegraphics processor136 may be handled by theCPU132 in some applications where the decoded video is passed directly from thedemultiplexer110 to a video encoder.Graphics processor136 is also coupled to thesystem bus130 and operates under the control ofCPU132.
[0025]STB22 may incorporate asmart card reader140 for communicating with a so called “smart card”, often serving as a Conditional Access Module (CAM). The CAM typically includes a central processor unit (CPU) of its own along with associated RAM and ROM memory.Smart card reader140 is used to couple the system bus ofSTB22 to the smart card serving as a CAM (not shown). Such smart card based CAMs are conventionally utilized for authentication of the user and authentication of transactions carried out by the user as well as authorization of services and storage of authorized cryptography keys. For example, the CAM can be used to provide the key for decoding incoming cryptographic data for content that the CAM determines the user is authorized to receive.
[0026]STB22 can operate in a bi-directional communication mode so that data and other information can be transmitted not only from the system's head end to the end user, or from a service provider to the end user of theSTB22, but also, from the end user upstream using an out-of-band channel. In one embodiment, such data passes through thesystem bus130 to amodulator144 through the tuner (operating as a return path OOB tuner) and out through thetransmission medium20. This capability is used to provide a mechanism for theSTB22 and/or its user to send information to the head end (e.g. service requests or changes, registration information, etc.) as well as to provide fast outbound communication with the Internet or other services provided at the head end to the end user.
Set-[0027]top box22 may include any of a plurality of I/O (Input/Output) interfaces represented by1/0interfaces146 that permit interconnection of I/O devices to the set-top box22. By way of example, and not limitation, a serial RS-232port150 can be provided to enable interconnection to any suitable serial device supported by theSTB22's internal software. Similarly, communication with appropriately compatible devices can be provided via anEthernet port152, a USB (Universal Serial Bus) port154, an IEEE 1394 (so-called firewire or i-link) orIEEE 1394wide port156, S-video port158 orinfrared port160. Such interfaces can be utilized to interconnect theSTB22 with any of a variety of accessory devices such as storage devices, audio/visual devices26, gaming devices (not shown),Internet Appliances28, etc.
I/O interfaces[0028]146 can include a modem (be it dial-up, cable, DSL or other technology modem) having amodem port162 to facilitate high speed or alternative access to the Internet or other data communication functions. In one preferred embodiment,modem port162 is that of a DOCSIS (Data Over Cable System Interface Specification) cable modem to facilitate high speed network access over a cable system, andport162 is appropriately coupled to thetransmission medium20 embodied as a coaxial cable. Thus, theSTB22 can carry out bi-directional communication via the DOCSIS cable modem with theSTB22 being identified by an unique URL (Universal Resource Locator).
A PS/[0029]2 or other keyboard/mouse/joystick interface such as164 can be provided to permit ease of data entry to theSTB22. Such inputs provide the user with the ability to easily enter data and/or navigate using pointing devices. Pointing devices such as a mouse or joystick may be used in gaming applications.
Of course,[0030]STB22 also may incorporatebasic video outputs166 that can be used for direct connection to a television set such as24 instead of (or in addition to) anIEEE 1394 connection such as that illustrated as30. In one embodiment,video output166 can provide composite video formatted as NTSC (National Television System Committee) video. In some embodiments, thevideo output166 can be provided by a direct connection to thegraphics processor136 or the demultiplexer/descrambler110 rather than passing through thesystem bus130 as illustrated in the exeplary block diagram. S-Video signals fromoutput158 can be similarly provided without passing through thesystem bus130 if desired in other embodiments.
The[0031]infrared port160 can be embodied as aninfrared receiver34 as illustrated in FIG. 1, to receive commands from an infraredremote control36, infrared keyboard or other infrared control device. Although not explicitly shown, front panel controls may be used in some embodiments to directly control the operation of theSTB22 through a front panel control interface as one ofinterfaces146. Selected interfaces such as those described above and others can be provided inSTB22 in various combinations as required or desired.
[0032]STB22 may include adisc drive interface170 and discdrive mass storage172 for user storage of content and data as well as providing storage of programs operating onCPU132.STB22 may also, include floppy disc drives, CD ROM drives, CD R/W drives, DVD drives, etc.CPU132, in order to operate as a computer, is coupled through thesystem bus130 tomemory176. Memory178 may include a combination of any suitable memory technology including Random Access Memory (RAM), Read Only Memory (ROM), Flash memory, Electrically Erasable Programmable Read Only Memory (EEPROM), etc.
While the above exemplary[0033]system including STB22 is illustrative of the basic components of a digital set-top box suitable for use with the present invention, the architecture shown should not be considered limiting since many variations of the hardware configuration are possible without departing from the present invention.
In general during operation of the[0034]STB22, anappropriate operating system180 such as Sony Corporation's Aperios™ real time operating system is loaded into, or is permanently stored in, active memory along with the appropriate drivers for communication with the various interfaces. Along with the operating system and associated drivers, theSTB22 usually operates usingbrowser software182 in active memory or may permanently reside in ROM or EEPROM. Thebrowser software182 typically operates as the mechanism for viewing not only web pages on the Internet, but also serves as the mechanism for viewing an Electronic Program Guide (EPG) formatted as an HTML document. Thebrowser182 can also provide the mechanism for viewing normal programming (wherein normal programming is viewed as an HTML video window—often occupying the entire area of screen26).
STB software architectures vary depending upon the operating system. However, in general, all may include at the lowest layer various hardware interface layers. Next is an operating system layer as previously described. The software architectures of the STB may include a next layer referred to as “middleware”. Such middleware permits applications to run on multiple platforms with little regard for the actual operating system in place. Middleware standards may be based upon JavaScript and HTML (HyperText Markup Language) virtual machines. At the top layer is the application layer where user applications and the like reside (e.g. browsing, email, EPG, Video On Demand (VOD), rich multimedia applications, pay per view, etc.). The current invention can be utilized with any suitable set-top box software architecture.[0035]
FIG. 3 illustrates a[0036]system200 for a providing a display of items pertaining to a user. Such items may include a television program or programs watched by a user, television program or programs to be watched by the user, an activity or activities in which the user has participated, an activity or activities the user is scheduled to participated, radio programs listened to by the user, radio programs to be listened to by the user, and so forth.
As shown in FIG. 3, the[0037]system200 may include a number ofdisplay arrangements202 each located in a respective home, office or the like. Eachdisplay arrangement202 may includeSTB22 and atelevision24 having adisplay26 which may be arranged in a manner as previously described. Further, eachSTB22 may be connected toservice provider10, theInternet44 and/or remote server48 (FIG. 1) in a manner as previously described. Additionally, eachSTB22 may include aninput device206, aviewer recognition circuit208 coupled to acamera210, atimer212, and a processor such as CPU132 (FIG. 2).
The[0038]input device206, which may be a keyboard or the like, is adapted to receive inputs from a user. Such inputs may include instructional commands pertaining to the set-up of thesystem200, viewer information, a television program or programs a viewer or viewers has watched or will watch, the addition of comments which may be added to a display as hereinafter more fully described, and so forth.
The[0039]viewer recognition circuit208, which may be coupled to theCPU132 and which may utilize theCPU132, is adapted to receive video inputs from thecamera210 and determine therefrom which person or persons are currently watching a television program. More specifically, theviewer recognition circuit208 may initially receive a video input image or signature from each potential viewer in a home or office and may store the same in a memory such as memory176 (FIG. 2). Thereafter, when therespective display arrangement202 is activated, thecamera210 may automatically capture a video image of the person or persons currently watching thetelevision24 and may supply the same to theviewer recognition circuit208, whereupon a comparison may be made between such captured image(s) and the stored signatures. Upon determination of a match, theviewer recognition circuit208 may supply the identity of the person(s) currently watching thetelevision24 to theCPU132. Theviewer recognition circuit208 may constantly monitor the identity of the person(s) watching thetelevision24 in a similar manner and may supply such identity information to theCPU132.
In the event that the[0040]viewer recognition circuit208 is unable to properly recognize a viewer, or in the event that the viewer recognition circuit is not included in aSTB22, information pertaining to the identity of the person or persons currently watching thetelevision24 may be manually inputted by the respective person(s) by use of theinput device206 and supplied to theCPU132. Additionally, such person or persons may also input information pertaining to the television programs which they are watching or have watched by use of theinput device206 which may be supplied to theCPU132.
The[0041]CPU132 may receive information pertaining to the identity of the person(s) watching thetelevision24 from theviewer recognition circuit208 or theinput device206, in a manner as previously described. TheCPU132 may also receive information pertaining to the amount of time a respective channel was “on” by use oftimer212, and information pertaining to each television program that was broadcast and received through theSTB22. Based upon such information, theCPU132 may generate a television program signal which is representative of each television program each person watched and arranged in a predetermined manner. Such television program signal may be supplied to thetelevision24 in a respective home or office associated with the respective STB by way of theinterface30 or to a number ofother televisions24 associated with other STBs located at other homes or offices by way of theservice provider10 andInternet44, whereupon a corresponding display may be presented on the respective display unit(s)26.
Examples of the above-described television program display are illustrated in FIGS. 4 and 5. As shown therein, the displays illustrate a plurality of television which were broadcasted along with highlighted[0042]programs300 which represent the television programs watched by a respective viewer (FIG. 4) and viewers (FIG. 5). As is to be appreciated, although only the three channels which the viewer(s) watched between the hours indicated are illustrated in FIG. 4, the present invention is not so limited. Instead, other arrangements may also be utilized. For example, all television programs broadcasted between the desired hours may be displayed along with an indication (e.g., by highlighting) of the programs watched by the viewer(s).
Additionally, a viewer or viewers may insert comments into a television program display. These comments may include comments pertaining to a particular program or to non-television program related items such as activities in which the viewer may have participated or will participate, and so forth. Such comments may be inputted by use of the[0043]input device206, whereupon a signal may be supplied to theCPU132 which, in turn, may generate a corresponding signal which may modify or be combined with the television program signal. An example of such a display is illustrated in FIG. 6. Further, a display may also be created which illustrates activities and/or television programs which a person(s) may participate in and/or watch in the future, as indicated in FIG. 6.
As indicated above, the present displays may be generated and displayed in the same home or[0044]office202 or, alternatively, the displays may be generated and displayed in more than one home oroffice202. In this latter situation, a group of people in a plurality of homes or offices may be established. Such group may be established by use of theinput device206 and destination address information (such as URL) pertaining to eachrespective STB22 of the group. Further, each member within the group may be entitled to a different privilege or level of access with regard to the display. For example, as illustrated in FIG. 7, some members may be able to do one or more of viewing past programs, viewing upcoming programs, viewing past activities, and viewing upcoming activities. Additionally, some members may be able to add comments and/or edit material contained in a display.
Although the above displays were described as pertaining to television programs and/or activities, the present invention is not so limited. Instead, the present invention may be applied to other types of items. For example, the present invention may provide an indication of literature which a user read or will read, radio programs a user listened to or will listen to, and so forth.[0045]
As is to be appreciated, the present invention provides a means wherein parent may monitor the television programs their children watch. Further, the present invention provides a means wherein people within a household or a group within a plurality of households may easily notify others of day to day events such as television programs they watched or are planning to watch, activities such as sporting events and the like in which they have participated or are scheduled to participate, and so forth.[0046]
Although preferred embodiments of the present invention and modifications thereof have been described in detail herein, it is to be understood that this invention is not limited to these embodiments and modifications, and that other modifications and variations may be effected by one skilled in the art without departing from the spirit and scope of the invention as defined by the appended claims.[0047]
